The correct 5L machine is the one whose station layout, extrusion capacity, mold space, and automation match your real container weight and target output. Do not select a machine from maximum volume or dry-cycle speed alone.
Start with the container specification
Before selecting a machine, confirm the container volume, dimensions, material, weight, neck and handle design, number of layers, mold cavities, hourly output, and required labeling or trimming process.
A 5L chemical jerry can, detergent bottle, and lubricant container may share the same nominal capacity but require different molds, die heads, cooling time, and auxiliary equipment. A product drawing or physical sample gives the machine supplier a more reliable basis for configuration.
Single station or double station?
A single-station machine completes molding on one side and is generally suitable for flexible production, moderate output, and projects involving more frequent mold changes.
A double-station machine alternates between two molding stations. While one station is cooling or releasing the product, the other can continue molding, making it better suited to continuous production when output is the priority.
Compare plasticizing capacity, not only cycle speed
Dry-cycle speed does not equal the final number of finished containers per hour. Actual output also depends on product weight, material formulation, cooling time, mold cavities, container shape, trimming, and auxiliary equipment.
A light household detergent bottle may cool faster than a thick-wall chemical jerry can. Output should therefore be calculated using the real container specification.
Select the mold, die head, and automation together
For a 5L jerry can, the supplier should evaluate mold dimensions, handle and neck structure, flash position, cooling-channel design, cavity quantity, and single-layer or multilayer requirements.
A complete line may also include material loading, a chiller, air supply, conveying, automatic deflashing, leak testing, in-mold labeling, robotic handling, and scrap recycling. The right automation level depends on labor cost, quality standards, and planned volume.
Compare Tongda 5L machine options
| Model | Station | Reference dry cycle | Extrusion output | Selection direction |
|---|---|---|---|---|
| HSE-5L | Single station | 1300 pc/h | 85 kg/h | Flexible production and moderate output |
| HS II-5L | Double station | 900 × 2 pc/h | 110 kg/h | Higher-volume continuous production |
| HTS II-5L | Double station | 700 × 2 pc/h | 110 kg/h | Stable 5L production with a compact configuration |
These are machine reference specifications. Finished-product output must be confirmed from the product weight, material, mold cavities, and cooling time.
Which configuration should you choose?
Choose a single-station model when production volume is moderate, products change frequently, or initial investment and factory space are important. Choose a double-station model when continuous output, lower idle time, and automated downstream handling are priorities.

Common buyer questions
What material is normally used for 5L jerry cans?
HDPE is commonly selected for its strength, impact resistance, and suitability for chemical, lubricant, and household packaging. PP can be considered for specific applications.
Is a double-station machine always faster?
It can reduce idle time, but finished output still depends on product weight, cooling time, mold cavities, and automation.
Can one machine produce different 5L containers?
Yes. Different molds can be used when their size and production requirements remain within the machine's technical limits.
Can a 5L machine support multilayer production?
Yes, when the machine is configured with the required extruders and a matching multilayer die head before manufacturing.
Final recommendation
The best 5L jerry can blow molding machine is not simply the model with the highest listed speed. It is the machine whose extrusion capacity, station configuration, mold space, and automation match the actual container and production target.
